This idea has been merged into another idea. To comment or vote on this idea, please visit PATCHMYPC-I-1303 Ability to create Custom App updates and base installs.
For software that has different installers for different languages it would be helpful to be able to change the download URL.
I would be fine with a predefined selection, in case you dont want to support fully custom URLs.
Is your end goal to be able to publish products which aren't in our catalogue? If yes, I recommend voting on this idea instead: https://ideas.patchmypc.com/ideas/PATCHMYPC-I-1303
In fact, I will merge this with that idea - because as it stands, your request would not be possible.
Changing the URL would invalidate the security validation we do in our catalogue, and it will also invalidate the detection logic. For example, if you changed the URL to be of different software, and the Display Name was different in the registry as a result, then detection would fail. To that end, this is why I think your request is really asking for the ability to publish custom software (software that is not currently in our catalogue).
