Undo last action in DevTools's Inspector

Hello! Is here any ability to undo last action in DevTools? Let’s say I deleted some DOM element or just changed some css property. How can I make a step back, i.e. undo my last action?
For example, in Chrome I can just Ctrl+Z, no matter what, how and where was changed, as soon as I focused in DevTools, my last action will be undone (a lot of steps back are available).
If there is no such feature in Firefox DevTools (I assume I just didn’t find it), how can I (or somebody more experienced in moz: community) make a feature-request?
Thank you!
