Inlay generator question

Great app. My question is about the pocket is it possible to have a 2 stage cut?

I am using a 1/16 bit to get the fine detail on my edges but also have to rely on the same bit to clear the whole pocket. 26 hours est.

I would like to know if I can use the 1/16 for the edges then maybe a 1/4 to clear the rest of the pocket.

can you share your file please and I will take a look 26 hours is to long at that rate a wood chisel would be faster lol
