Extrude Multiple will be available from 3.8.4

Feature Description

Extrude tool is one of the most frequently used tool in Designer Tool but it allows only one polygon to be extruded in a normal direction of it.
So In order to overcome this limitation Extrude Multiple has been added to support extruding multiple polygons in individual normal directions, average or x/y/z direction.
