Is there a way to automatically assign newly-created units to control groups?

As an AoE2 dilettante, this is something that I miss immensely.

For example, I'd like all newly-created archers to go into group 2, so I do not have to manually add them.

In any given game, one of the most frustrating things I have to do is to periodically select a group, shit-select some newly-created units (hopefully they have not dispersed yet due to their default aggressive stance!), then control-rebind the new group, and set their stance to defensive. It feels like a big overhead and waste of time.

Does everyone else have this problem, or do they manage groups differently?
