Unlink Visio/AutoCad File

1. Some changes came which were made in BOQ.

2. The drawings are in Visio file, called Drawing_v0.vsx

3. If I duplicate the drawing and name the new one as Drawing_v1.vsx and start making changes there it would be fine.

4. Now I want to review my previous dwg copy v0, but if I open it, any thing deleted in BOQ or changed will be updated in v0 copy.

Would it be nice to have an option to unlink a particular file from D-Tools BOQ so that it would just be a Visio file with shapes and static data only.

So if I duplicate v0 dwg, save new copy as v1, and then unlink v0, I have proper dwg backups, not just a pdf for my drawings.

I understand, one risk here is if someone by mistake right clicks a current file and unlinks it, there might be impossible to link it back, or maybe it might be linked again using component ID field in shapes.
