Saving USD file during crash

[gracekumagai]

When Maya is able to save during a crash (for example, #2339), it attempts to save the maya file in a tmp location. After the pop-up for the maya file, the user is prompted to choose how to save the USD file.

For our workflows, we recommend that the artists select the 1st option (save maya file and usd file separately), however, I think this overwrites the USD file (instead of creating a tmp copy).

We were wondering if one of the save options would allow the user to save both a tmp version of the maya file and USD file? If not, would it be possible to add the option (something similar to the maya "Fatal Error" popup but for the USD file)?

Overall, our users want to save a copy of the version that crashed and do not want to overwrite a functional version of their files (maya and USD) with one that potentially crashes.

Here's an gif from #2339 showing the popups:

Thank you so much!
