Alright, here is what I would normally do:
Say for example you just started off with Pyromancer and want to change random gear. You unequip that, load the Item Swap script and drop the heavy boots (as example), on the table it is shown the last item dropped.
Where it says the item name on the script, you double click that and you get a LOOOOONG drop list of many other items, the quickest way to get the items you want is to type it in and click the arrow down
For example, type in: "Black Tights" and click on the down arrow beside the value box to initiate the list and you can choose up to 0 to +10 or in the case of the Black Tights +5 since it is a Twinkling Titanite upgrade. Choose which one you want and pick the item back up and you will have the swapped item.
I wouldn't know what you would want, so make sure to use a wiki to research your items and then you'll get your desired gear rather quickly without having to spend time looking/grinding for them.
That's how it works, but there are a few tables that rather inputs the items straight into your inventory without the need of swapping, but those are around GitHub somewhere and I'm too lazy to gather them up.
