Extrusion path issue

Hello community,

we are trying to extrude a circle along a curved path. As you can see in the video attached, we first define the reference circle face to be extruded that respond to specific geometrical constrain (it has to be tangent to the magenta lines in the video) but this led to the first problem: it finds all 4 possible circles that fit the constraints and every time we have to manually input the correct one, for the starting point and the end point of the extrusion path. Is there a way to automatically recognize the correct circle? After that, since the last release, we also have to confirm the direction of the extrusion, it is not automatically recognized as in the previuos FD! Could someone help us?
