Fast frequency sweep with the PLUTO in GNU Radio

Hi,

I would like to sweep through a band of several hundred MHz with the pluto but am unsure on two issues:

1) Is there a way to speed up the LO change,

2) Can a command port be added to the pluto source block (akin to to the USRP block) to facilitate this change within GNU Radio companion

Apologies if I have not added enough detail, I am relatively new to this area - please ask questions to help clarify.

Kind regards,

Alex
