Like when you go to accept a reward for deliveries and you're close to max (seals or scrips) it'll tell you and warn you that you wont get all of the reward.

I was wondering if we could have our duty finder do that too for things like our Tomestones.

vague wording example:
"It is possible you will not receive all of "X" Tomestone for completing this duty, do you confirm?"

Thank for you reading
