Test Sat in Dev?

What would the chances be of being able to get a test satellite added in Dev with some frequencies assigned in the amateur spectrum? I’m almost done at this point, but it would be helpful to be able to have some such options where I would receive other transmissions or inject signals to set and tweak levels a little easier.

I couldn’t find anything in the documentation, but it is of course entirely possible that there’s a much simpler way of doing this than testing on passes directly.
