Replace older version of an asset with the same name

When you try to upload a stamp or texture that has the same name as another one in the catalogue, the upload simply fails with a message asking you to change the name of whatever you're trying to upload. It would save some time to have an option to "Replace" an existing asset. Sometimes, I just want to replace something with a better version of it (higher res, more optimised, slightly modified, etc.). And of course the names are identical.
