Please add keyboard shortcut for rectangle tool

[zxcvpoiu]

Hi :D,  i would like to use “M” key to quickly switch to rectangle tool, just like i used in other design software for so many years because i’m design outdoor signal and use rectangle tool very often.
But in affinity designer for ipad i cannot do it. I have to reache to the panel then click on the rectangle tool icon. That’s a little inconvenience because it slower.

Maybe next update The Affinity Team can add this little feature ? Thans you for reading this !
