HL/TA dashboard - how do you register as a manager?

[Nemo]

I've got my first enquiry via HL/TA for the property I manage. When I created the listing it didn't give me the option to list as a manager, but I'd rather be upfront if I can.

I will be creating two listings for my own properties too and want to be seen as the owner on those. Anyone know if this is possible with the new dashboard but from one account?
