P: Possible to see Heal tools with finger in way

I find it extremely annoying to use Stamp/Remove/Heal tool in mobile Lightroom app. When I try to mark desired area of my photo to stamp it, my finger is covering the areas I'm marking. So I don't see what I'm doing... It gets very hard especially when I want to be precise, so when I use very small brush.

Very very annoying.

Why don't you update the app, so when using the brush tool with a finger, next to the zone which I touch with my finger,  a "cloud" with live preview appears, so I can see what I'm currently "brushing"?
