The first thing to check is to see if the item has a smoothing modifier applied, already (it affects the item as a whole, so you do have to be careful with it or it can mess details elsewhere on the item). It can be found under Parameters. If it does, often upping the number of iterations will clear it up. If it doesn’t selecting the item in the Scene and going to Edit > Object (or Figure) >Geometry > Apply Smoothing Modifier…
Sometimes, adjusting the weights with the Weightmap brush can help, but that’s more of an ‘advanced’/last ditch way.
Taking it to a modeller and creating a custom morph is the best ‘permanent’ fix, though. And pretty much, that’s what the Hexagon bridge is for…
So…simple answer…no, not as fine of a control, but not exactly nothing to do about it, either.
