@oliver-jazz , We agree signal IR is been the major component these days for the advanced app services. The feature you were looking for is also been considered as a valid suggestion and been triaged in our feedback section.
I recommend you to upvote it and other features that are of interest. In general, Azure feature team would check feasibility of a feature request, triage it, prioritize against existing feature backlog, add in roadmap as appropriate and would announce and/or update the related Azure document once a feature request is addressed.
Meanwhile, I will check about the ETA for this feature internally and will update accordingly. Please stay tuned!
