Currently the options are a proxy folder next to the original source or a custom folder.
There is no control over the naming convention.
We have a workflow that would work better if we could store the Proxy in the same folder as the original (no sub-folder) and a naming convention that tags a "-Proxy" (as opposed to a "_Proxy") to the original name.
Overall what we're looking for is a more sophisticated Destinations system for PPro and AME.
Way back in the FCP-7 days they divided export presets into two types: Render and Destinations.
Perhaps Adobe's "Ingest" presets are related to FCP's "Destinations". What Adobe's lacking is the sophistication of the location and naming conventions -- an ability to control prefixes and suffixes, locations and dynamic options. Or is that already in there, and I'm somehow just not seeing it?
