How to collect all necerry to export sbsar?

When I try to export sbsar to use in Painter  I almost always get some  criptic yellow message and refuse .   Is there a simple way to make sure evrything involved is duplicated  to same  package ?  

Or maybe a way  to kill those  things in sbs file that shows yellow triangle?  

Sbs came as a single line  xml file  that is very inconvenient to edit in text editor. 

How can I make  those yellow  references  disappear  in sbs without breaking anything.  

Does anyone have a pyton scriot that could "clean" the sbs from unused  resource links?   Because  very same sbs works just fine in Designer itself.  So my guess those missing resources are redundunt .

Wonder should I try  to task chat GPT4  for that.? Does anyone have an experience to share?
