Overwriting the review links and accessing the Team slides

Hi, 

We need guidance on consolidating our Articulate 360 Teams access for project collaboration.

Currently, our team of 10 users is working together on a single project. However, we have two separate Articulate Teams with five users each, purchased under different purchase orders.

The 5 users in same Articulate team can share team slides or overwrite the review360 links. 

We would like that all 10 users to be able to leverage the full benefits of a single Articulate Team, including features like shared team slides and Review 360 link management.

Questions:

1. Is it possible to merge these two or more existing Teams under a single subscription, even though they were purchased under separate POs?
2. If merging is feasible, what's the maximum user capacity for a single Articulate Team?

Any insights on how to best achieve our goal of seamless collaboration within a unified Articulate Team environment would be greatly appreciated.
