Is there a way to make a Weapon/Armor Select in RMMV?

I wanted certain bosses in the game to drop a unique weapon or armor for players to use, but I ran into the problem of having the weapon become obsolete. I didn't want to make the weapon scale with a stat or your level, as there would be little to no reason to use standard weapons or armor. To solve this I made a location where you can spend resources to upgrade the weapons. The problem I have now is finding a way to select which weapon to upgrade. I like the way the 'Item Select' event command handles item selection, but there's no way to do the same for weapons and armor. Is there a script or plugin that creates a similar effect, where the player must choose a weapon/armor of a certain type from their inventory and depending on the weapon/armor they would get a different result?

Here's a plugin that allows you to do a "Select Equip" which is basically the Select Item but for weapons and armor.

It doesn't come with a help window to describe the equip as you're selecting it, so I wrote an extension which creates a help window for that.

Thank you so much! I'll be sure to credit you for both your help and your extension plugin! :)

To download from Github, basically you just click the link to reach the Github page, then right-click the "Raw" button and select "Save Link As...".

Here's an example:

Edit: Ah, looks like you figured out the download. Well, this comment looks silly now but I'll leave it for future reference.
