[Feature] Add filtering to source for Item Count Tooltip

[Infinitay]

My personal use-case for this plugin is primarily to find out what items I have stored in my POH and sometimes my bank. Currently, I'm clue hunting and I want to fill up my POH storages with clue items of 1 of each item. However, it's incrementing the count based on every source for the item. I would like to request a feature to add a new tab menu of toggleable options from where the item count should be incremented by.
