Brushes have their place.
When I was helping a mate do up his "pad", we put trunking down the walls for "to be decided when we put them in and liable to change" cables - aerial, speakers, HDMI, network, ... Rather than leave a galv box showing he used brushes, but he has a bit of a humorous side to him. Needless to say he had people coming round to see how it ended up - and they'd ask what these funny looking plates were. Before there were cables to give the game away, he'd tell them they were toe ticklers - and people believed him
As some blank plates are thicker than others may I suggest a trip to somewhere like b&q where you can take them off the shelf and see if the edge will be thick enough to file a slot into. the old style MK square edge ones (if i remember correctly) used to have almost precut areas to enable you to do just what you are proposing
I too prefer the alternative to brushes; and in my own home, am happy to weild a soldering iron!
...and I'm sure some will see this and think, maybe brushes are better!

Indeed one can, but one is then paying for the terminals etc. (and cable restrain) when all one really wants/needs is the plate and a hole.
I may be wrong, but I have a vague recollection that I've seen blank plates (no terminals etc.) with a sort of 'knockout" (wall, a thinner bit of material to file/cut) on the edge for a cable entry. Did I dream that?
