Yes Edwin, This is possible. in case there is a repetative pattern that can be represented by main blades and in between a sequence of splitter 1, splitter 2, splitter 3,.. you can define it this way and then you can select the finish for each splitter apart.
if there is no pattern - the interaction to the geometry selection is less straight forward than usual.
The Roughing and Hub Finish operation will need to have as "Blade" the two blades between which you want to cut. you can also select multiple blades at once.
For Blade / Blend finish operation you will have to select as "Blade" the blade you want to finish. adjacent blades from both sides - select as check.
always set the Number of Blades to be 1.
since every operation requires a different selection of certain geometries, I'd recomend to populate the Multi_Blade_Geom with the selections you do today, but do not select Blade an Blend. Nor select Check geometry. (don't forget to set the # of Blades to 1)
by doing so - each operation will allow you to populate the blades you want to work on or in between explicitly.
Try to use it this way and if you face issues - either contact me directly email@example.com or if you think that the questions will interest others - post those here.
