more than one call sign for a user (DMR / APRS)

[M0JFP]

Hello,

Is it possible to register more than one call sign for the APRS / DMR gateway under my account.

I'd like to add

MB6ICI (dv4 mini node) ID 2341433
MB6IJP (dv4-mini node) ID 2341259
M0MXO (club call) ID 2341550
My USA call sign WO2I ID 3153078

Thanks very much

James
