Garmin coach adaptive marathon plan

Hi, I see several post like this but nobody answer this, maybe there is no answer after all, but I am going to post it anyway as I believe many of Garmin users have similar question. 

So, is there any plan in the future to have this adaptive marathon plan as the HM, 10K and 5K. Would be great you know for beginner-intermediate runner like myself.

Cheers,
