Running multiple instance of a sandboxed (isolated) application?

I have a client that wants me to use an Authenticator App that I _already_ use for work **AND** home. Currently I'm using [Shelter](https://f-droid.org/packages/net.typeblog.shelter/) to provide work and home, but it's limited to those two "profiles". The functionality provided is fine, but I need _something_ that provides more profiles or units of isolation? Is there any work around? Magisk is allowed. The phone is also rooted.
