Customising the filiament start routines on Ultimaker 3 / Cura

[Rharrison 2]

I'm having a real battle on with getting the PLA to stick after setting up a big PVA support bed for printing. Often the PLA doesn't flow right at first for a few spirals and knocks the whole print out. Ideally I would like to create another brim, the width of the prime tower, just to get the PLA flowing. It doesn't need to grow with each layer just the initial PLA start a bit like the old blob but rather than blob just about 20 concentric circles on first use on layer one.

 

If this is something I can do myself by editing the GCode or such like, a little pointer on how to do this would be great.
