Calculate Grid Import without solar export

Maybe I’m just having a mad math day, but I can’t figure this out

I’m trying to get a calculation for only grid import. I want to see how much power I actually use from the grid, and I don’t care about how much I export

For my Grid (In and Out) I have this

Is there a way to have that calculation, but to only show positive values?

I have an integrator defined as below:

Grid Wh = Mains1 + Mains2

And then have two outputs for export and import:

Export Watts = Grid.neg abs
Import Watts = Grid.pos

Please see the docs description of integrators:
