My Idea of Discussions, Should The Pip-Boy [Build/Destroy Tool] have a selector loadout button so we could select to change a Sentry, Dispenser or Mini-Sentry for a option.

How it works is the tool will have it's own menu, you can change the Sentry and Dispenser or Mini-Sentry if you the Gunslinger place to place how ever you like you to do like you change each loadout in your class each time.

This is only a what if so we don't if Valve is going to add them. Workshop engineer builds if they were added in the game with their own PDA like the LED Sentry, The Energy Sentry, 'Big-a-Boom' Howitzer Sentry Gun, The Rayzar, Mini-Dispenser, The Artillery Sentry, The Defensive Engie Pack, The Energy Sentry, R-CAT, R-CAT MKII, Dogs of War and The Vending Machine they also would be your selection to change your Pip-Boy loadout if they were added in the game.
