How can I auto-convert .vss files for use in Draw? (I have Visio 2010 and .vss files)

[IT_Architect]

I have Visio 2010 that ships with tons of useful .vss stencils plus all manufactures make them for their own products. Is there a way to auto-convert them for use in Draw other than manually populating them one at a time in Visio, one at a time pasting them into Draw drawing, and saving it as a template or one at a time adding them to a theme? (I’ve tried online converters, and they say I should be able to open up and see them in any browser, but I just get a blank screen there or if open them in Draw)

If someone already has that I can buy, I’m open to that too.

Thanks!

Try to export them (from the Visio) into a more compatible file format. (Meta files - for example)
.
If you upload (share) one or more of these files here, then we (maybe) will able to search/find a solution or some workaround. (I have not any .vss file)

The LO Draw can open such Vision files:
