Separate flow ratio for infill vs walls

As per the title really, can we get a separate flow ratio for infill vs walls?
I guess this could sorta go along with the requests for seperate material for infill vs walls as it could be done in the slicer that way - but plenty of my prints have infill twice the extrusion width that the walls are, which leads to a little more hotend pressure and slight underextrusion even at the same flowrates - it’d be nice to have a modifier just like we already have for bottom and top surface flow ratios, but for the infill, to be able to correct for those situations and similar.
