[Closed] FaceMatID Loop Problem

Hi,
I’ve written a script that cleans a multimaterial subduplicatematerials, mainly to clean up the mess after attaching multiple objects that had mutli-sub materials.
It is working as intended but I’m facing a bit of a problem:

for k = 1 to $.numfaces do (
			idm = getFaceMatID $ k
			if idm == $.material.materialIDList[i] then (
			setFaceMatID $ k $.material.materialIDList[j]
			)

This is the code that I’m using to switch the FaceIDS that happen to be different, but link to duplicate materials.
The problem is I’m attaching a lot of objects with a goal of a fairly large object, as I attach more, the face count gets bigger and the performance is becoming sluggish/non responsive.
The question is (and I’ve searched the manual all over the place but couldn’t find) there a command that will function as the “Select ID k” Button in Editable_Mesh?
I think this will improve the performance greatly since I don’t need to cycle through the entire face count to find what I’m looking for, something like this:

select $.faces.matID[k] --or something

Thanks.
