Option for update or new object?

[Lustwaffeln]

Please excuse if a unecessary question...

I am trying to put new life into existing rigs of mine, made in Blender, using the GoB pipeline.
Is there a option or possibility to update the existing geometry when exchanging between B/Z? Like it is an option in the DAZ to ZB bridge to import the geo as an update to the existing geo or to introduce a whole new object.
Because, of course, all my binding is gone when I import from Zbrush back to Blender.

Thank you for your work, regardless!
Sincerely.
