As cinaira pointed out, the feature is not currently available, but it might be worth picking it up as a wider point as there have been a bunch of similar questions over the past few weeks. I don’t work for DAZ, but looking the store implementation from the IT side, not just the customer side, it’s clear that a lot of the implications of changing the store just aren’t obvious to people who don’t have the IT perspective and it might help to lay them out.
The old DAZ store was very heavily customized to suit our needs, in fact, as I understand it, the entire store was developed in-house, which is almost unheard of. The reasons for replacing it as unmaintainable are undoubtedly sound, I’ve been responsible for maintaining an obsolete, extremely complex programme with no support and it was a nightmare, software like that reaches the point that the slightest change risks bringing the whole house of cards crashing down around your ears.
So the old store had to go, and the only reasonable way to replace it is with a commercially available package, as then the vendor is responsible for maintenance over the longer term even if DAZ handle the day to day stuff in house. That’s a plus point, it means we get a reliable store once the initial teething problems have been dealt with (I think they should have been dealt with better, but that’s beside the point). The downside is we get a generic replacement, that doesn’t include customized options like only showing one or the other of the PC and MAC files, and a lot of features of the old store would count as customized. It’s possible DAZ will eventually customize the new store to provide this feature or that feature, but they need to crawl before they can run, so don’t hold your breath waiting for them any time soon - though DAZ-soon might well apply!
Some features of the old store we may never get back, if I was in charge of the implementation of the new store I’d certainly be arguing for the minimum level of customization possible, because the less customization the more reliable the store will be. That may sound harsh, but ultimately people (us!) will adapt to the new store, adapting the new store to the people may be less wise and ultimately make the store more unreliable/less easily updateable, which is where we came in!
