Pressure foot for inventables

Hi there,
I have few problem whit my x-carve when I’m working whit thin play wood (4/5mm). Even if I do my best to store the plywood as flat as I can, whenever I use it it is slightly bended so some parts during the cut rises and get ruined (even if I use the tabs). So I was wondering if there is a pressure foot that can be used with the x-carve

what i do in situations like this is just use double sided tape to hold down the material while you cut it. Also using a downcut end mill can keep the material from wanting to ride up the end mill. An upcut mill will pull the material upwards
