Guitar Cabinet Impulse Responses

[Impulse Response]

I would like to know exactly how to load Guitar Cabinet Impulse Responses into Multitrack DAW.
I run my outboard tube preamp into MT DAW, and it sounds good but...
The Cab IR is what I need for the final sauce.
Please help me conquer this last piece of the pie.
I am interested in help from Harmonicdog, and anybody else who knows from their experience...I'm working with the Iphone 6S, and not looking to max out memory, but I realize there may be some workaround required between apps.

I'm thinking you could load fiddlicator in the IAA tab of the track or master (if you want it on the whole song) and load the IR in fiddlicator.

Here's the link to fiddlicator

That should work I think
