Cadenzas with no attribution to original work

[justforplaying]

I would like to ask where I should upload cadenzas that has no indication of which work they are written for...
For example: Composer A wrote a cadenza that's for a work that has no indication on the cadenza.... The cadenza also never states what work it is written for, thus no info about the work is preserved...
One of the admin suggests that it should be uploaded in Anonymous page, but it is sorta weird, as the work itself is not really anonymous
Any OTHER admins can help with this? Where should I really put?

In that case I would suggest uploading it as a work by "Composer A" as a "Cadenza" (although if there are more than one, you will need to disambiguate them in the title, using the key/instrumentation, as appropriate).
