How to remove solder mask from bottom layer for heatsink

What is the correct way of removing the solder mask from the bottom layer? I need to place a heat sink under the thermal vias for an IC. Should I use a fill or a solid region and then change the layer to "Bottom solder"?What would you recommend for doing such a thing?

A fill is a rectangle, period. A solid region can be in any shape.Select the bottom solder first and then place either.Alternatively, if you have a shape in copper, you can just set the solder mask expansion to "rule" or set the tickbox in manual to add a defined expansion.
