When you enter into the manage draw participants screen, you're able to see everyone who has accepted the draw / is still in the draw, and those who are not in the draw.
What can't be seen for the trades who are not in the draw is whether they previously were in the draw but declined to bill.
Currently in order to see who has declined to bill, you need to go into the ‘close draw’ screen where you get the information.
It would be great to be able to see more information on whether the trade has ever been in the draw / if they had declined to bill for that draw so they aren't added back multiple times under the impression they may have been missed from being invited.
