Warp Tool. In photoshop it's Liquify.
Add a Photoshop "Liquify/Warp tool" node to designer.

https://share.allegorithmic.com/libraries/2728 here you go. But if you want tool this probably not going to happen because tool will destroy procedural aspect of designer. And is you want to destroy procedural aspect you can just use other software for warp.
Also there is several nodes for warp by default.
Let me add, a warp node like the mari Warp tool.
