AutoInput Accessing tile array in systemui

Hi all,
Awhile back I wrote tasker routine to toggle my mobile data using the autoinput click action and the text property to find the correct button (the carrier's name). When I went overseas last week the routine failed because the carrier's name changed and I'm trying to make the routine more robust by using the button's ID instead of its text.
After considerable fiddling, I believe ive worked out that the button is nested on a tile pane, and I'm not sure how to format the ID to access elements located in a tile. The ID that I got by querying the com.android.systemui (quick settings) is:

com.android.systemui:id/tile_label,index:28

Note, I think the comma is what is stuffing me up as I think that is the index of the element nested in the tile.
Cheers,
Rob
