[Scip] Solving the root node with pricing and then solve as an IP

Hello,

I want to generate columns only at the root node and then solve the problem with the current set of columns using branch and cut and variable branching. So this would be similar to just printing the problem and then reading it in and solving with a solver like CPLEX or GUROBI.  
I tried to deactivate the pricer with SCIPdeactivatePricer but you are not allowed to do that in the solving stage. Unfortunately there is no function like SCIPsetBranchruleMaxdepth where you could set the depth of the pricer. Btw. wihy isn't there? You might have some partial/inexact pricing you want to do early in the tree.

Thank you
Sebastian
