Garmin coach marathon training plan with strength included

I've just started a Garmin Coach training plan for an upcoming marathon. I was excited to see with the new update that you can now have Garmin Coach strength training plans. For obvious reasons, I'd like to include strength training in my marathon training plan. I can't see a way to do this. It seems I can either have a running plan or a strength plan, but not both. Is that correct? Is there a way to have strength training built in to my running plan (ideally), or be able to have a separate strength plan (if not)? 

Thanks
