Can I have multiple Hosts or Alternative Hosts use one license (but only one at a time)?

[Coraumy]

We are a small non-profit with one Zoom Pro license that we use for meetings and workshops. I am starting a new program that will involve up to 20 different small-group, peer-led meetings throughout each month. I would like for each small group leader to host the meeting (with screen share and recording capability). I know I could start each meeting as host, make the group leader co-host, and then leave, but that's a lot of work and I'm doing this on a volunteer basis. Are there any alternatives that won't require us to purchase a license for each individual group leader? That would be cost-prohibitive for us. 

For example, could we purchase one more Pro license, add all of the group leaders as users, and use that to assign them as Alternative Hosts when we schedule the meetings?

Thanks for your ideas.
