Differnent patch prefixed do not create unique patches

[melvin-ibuildings]

When trying to create patches for different applications that use the same database i tried to make the patches unique by giving them their own prefix. However this did not have the desired effect.
Sitiuation:
one patch with normal "Patch" prefixed already updates.
one newly created patch with the"Patch_cms" prefix.

When executing dbpatch status no new patches are found.

When looking at the database the unique key of a patch is patchnr + branche so for dbpatch both patches are the same as they both have patch nr 1 and branche default.

It would be handy if patch prefixes can also be used as an unique characteristic to a patch file
