No.

Describe the solution you'd like

I would like to be able to import all of the equipment from my stash with a single button so that I can easily farm for a while then use pob to quickly see the impacts of the gear farmed.

Here are some examples of similar tools that could be adapted to make this possible.

here is one page from my own stash which could possibly be transformed and added to the .xml file in the /builds folder.

Describe alternatives you've considered

Honestly, I considered taking this project on myself but I would be starting from barely above scratch to do it. If one of you would like to mentor me through the process I would gladly accept the opportunity to learn how to contribute to a project.

Please, if you are one of the devs and you don't mind doing a bit of hand holding I am very willing to learn and start implementing this. Here is my discord blahblahdrugs#2538

Additional context

No response

Start with the Path of Exile developer documentation for the stash API and inspect the example stash response linked in the issue. Then examine the existing /builds XML format; done would mean a user-facing import flow that converts all stash equipment into a usable build without manually copying items.
