AUSST Substance Painter SAP codes (minor versions)

We're looking to get AUSST to download version 7.4.1 of Substance 3D Painter which was previously grabbed via the (all versions) code of SBSTP. Looks like that specific version has since been removed so we're looking into adding it back using the version syntax for SAP codes. I believe that would be SBSTP#7.4#7.4.1, but so far no dice.

We've tried the following:
SBSTP#7.4#7.4.1

SBSTP#7.0#7.4.1

SBSTP#7.4.1

Both fresh and incremental. AUSST happily grabs 7.4.2, but we've got some version specific tools that require 7.4.1 and would love for that to be available for self-service installs via CC Desktop.

Any ideas?
