Is your feature request related to a problem? Please describe.
I ran into a problem with detecting when fishing lure is applied to a fishing pole with the new Dragonflight profession system, since it is no longer in your mainhand, but in the profession journal. I outlined the problem here in the WeakAuras Community discord, just linking it as to not make this ticket gargantuan.

Describe the solution you'd like
Under trigger Item>Weapon Enchant / Fishing Lure>Weapon , add the fishing journal fishing pole (slot 28) to the dropdown so that temporary enchantments from lures can be detected on it without requiring custom code

Describe alternatives you've considered
I can't think of any that'd attack the root of the problem I ran into, technically a field for specifying what temporary enchant is applied under trigger Combat Log>Enchant Applied would also work since it can only detect that an enchant is applied over what enchant is applied, which doesn't leave room for detecting if you are using a 10 minute lure or a 15 minute lure.

There's no api for getting temporary enchants on arbitary item slots, the api only works for main hand and off-hand. That's a wow limitation.

Darn! Worth a shot. Thanks for the reply!

You can always report that as a bug to blizzard, since after all the fishing lure is currently not conveniently shown in the default ui.
