Set default permissions before creating a new plan(s)

When creating a new Plan, under "Plan configuration >> Permissions" tab the following permission gets created by default:

Users	View	Edit	Build	Clone	Admin
<bamboo-admin>

Other	View	Edit	Build	Clone	Admin
Logged in users
Anonymous users

It would be interesting if you could set up default permissions to be used when creating a new Plan.

Example, having users under the group group-a where they have access to edit plans. As a result, when creating a new Plan, the following would be added automatically to the "Plan configuration >> Permissions" tab:

Groups	View	Edit	Build	Clone	Admin
group-a
