Teams admin centre - add the ability to setup a team completely (shared channels and/or groups)

I think the current teams setup workflow in admin centre is a bit flawed.

We're trying out to create a team for every project that we do, but since these projects are done by many different departments it makes sense to use Shared Channels within each project and divide the data in such a way that it is stored in the site library of the channel that is the most fitting. For example creative documents in the channel for the creative department, and business documents in the business channel.

To make things clearer to the end user we would like to structure each project the same. So it would be logical if an admin could create these shared channels while creating the project and not have to trust that a project manager is able to set things up correctly after they get assigned. (so being able to create a template would be nice...)

So IMHO what is missing from admin centre:

-ability to add shared channels.

-ability to add teams (in this case department teams) to these shared channels.

-ability to create a template with shared channels configured (is a little bit complex, because channel names need to be unique, so some sort of variables need to be taken into account... maybe these can be distilled from the main project team name...which is basically what we also intend) (maybe this could be done with Power automate if the ability to create shared channels is being added to an admin's abilities...)

Another option, which would actually be much sweeter would be to skip Shared Channels altogether and add the ability to add Office 365 groups to the main Team, now we can only add members... I would like to work with Team groups, as it's much easier to manage and remove a user from a group than to have this user have to be removed from each project individually. But actually I think both options are a necessity...
