You can find these using the filenames (if you already own them of course). If I had a few minutes spare I'd write a little script for this but unfortunately I don't at the moment.
You can use a tool like "Everything" - this is great app for finding files.
If you look at Eva Generosi's clips you will see that the filename for the standing explicit card is: in the format fddd_325dd.vghd where d is a digit.
There's full details of the naming rules in this thread:

32 means - accessory
5 means - explicit
So... if you search for files containing vghd and _325 you will find more. For example I just found these cards:
... then there will be other combos of filenames as well.
