Sometimes, you have do for example of `count` of polygon feature class A, polygon feature class B and point feature class C within the same polygon say Polygon 1 and you want the counts (as well as area and statistics) in one feature class as well.
So, in such a case, you have to run the tool multiple times (leading to several layers created in the middle first for polygon A count, then for polygon B count), before the getting all the counts (including area and/or other statistics) in one feature class.
It would be nice to have an option to summarize multiple layers at the same time along with having the option to set output field names as well.
