Centre of map in Basecamp

[Riktus]

Hi
I searched the site but couldnt find the answer to this. Is it possible to get crosshairs as a centre of map reference on Basecamp (I used to have this with Mapsource but moved to a Mac so no Mapsource option any longer)

Thanks in advance.

All the other features of Basecamp I am slowly getting used to.

Cheers
Rik
