Always "handy" is you add a Poll when you start a Sugg Thread, like that we can quickly vote without being "obliged" to post...
But, yep, Support: => +1.
I don't send such "huge bulk Trades" myself, but I send "fairly large Trades" also, and I see another Usecase for your Sugg:
When I send a Trade myself to some other Player, I try to send a "Quality Trade"..., => I read their Trade Rules (at least the parts that are not in ]size=85[ or smaller, or Yellow/Grey/Pink/Green on a Green Background, ah-ah...!

), and I check several Pages of both WL's (often 10-20 Pages or more) to include "quite a few" Pets, same with Items also maybe, to try to make the Trade "Interesting" for both Sides...
And I write a "personal" Msg, not just "Trade?"..., if Items are involved, I mention that I've been "careful" to select only Items they have x2 or more, if the Items are "a bit older", I also mention from which Year(s)/Event(s), etc..., and for the Pets, depending on the "Experience" of the other Player, I sometimes also explain a bit "the Maths" for the Trade, etc..., but I often spend 30 Min or more on a Trade...
But then, when I am ready to send the Trade, and I "finally" click on the "Send trade" Button, ... I regularly get the "One of the Pets has been moved and is no longer available" Error Msg, and the Trade gets auto-cancelled, with no way to get back to the Trade to try to edit it to remove the "offending" Pet(s) that is/are not available anymore...
And I think at that moment, "Oh...!

, grrr...!

, arrrggghhhh...!

, grrrr....!!!

", and I usually just give up, as I don't want to go and spend another 1/2h going through the same 10-20 WL Pages again to try to reconstruct the Trade...
=> Would be nice if Trades could be automatically or manually saved as Draft, maybe when we get the Prompt about the Trade being cancelled, with an extra Option like: "Do you want to save a Draft Version of this Trade if you want to edit it?"

"Pragmatic Thinker"...
I don't try to read anymore when Users use ']Size=85[' (or smaller...!) on the Forum or in their Trade Rules..., as this is completely unreadable on Desktop in any Browser...!
