Opening Multiple Sessions in Persona

Hi - We got Persona 2.00 on our EWM environment , we have some reports where on the output user open new window in normal SAP GUI, e.g. hotspot on material number open a new window to display material master. but when we try to do same in persona , it gives error that "Maximum number of sessions reached". We checked in back-end SAP system in  SM04, there is only one session opened for the user. Is there any configuration to allow maximum 6 sessions (like SAP GUI) in Persona, or persona allow only one SAP window to be opened at a time?

Thanks.
