Is your feature request related to a problem? Please describe. LC_SAMPLE_AP_MID is out-of-family with most MIDs for doing simple processing (like SEND_HK, etc) in that it has parameters. This is fine until you try to send it from something like sch_lab which doesn't support command parameters.

Describe the solution you'd like Add a simple LC_SAMPLE_AP_ALL_MID w/ no parameters (size 8)

Describe alternatives you've considered None

Additional context None

Alternatively could just use current MID but if the size shows no parameters just call w/ the full range. What's the preference @dmknutsen (or others)?
