Adding less than $5 "gig extra" on active gigs?

[wait4pawz]

Hello, I have found that I cannot add a gig extra on for less than $5 and I would like to suggest that this be reconsidered.



I understand that base gigs are a minimum of $5 and that is great because I don’t have to compete with someone else’s gig who is offering the same thing for less than $5.



BUT, if a gig has already been started/is active, I think that if I offered my buyer a gig extra I should have the option to choose below $5. Example (1): my buyer wanted another version similar to the one they just bought… I wanted to offer to do another version for an additional $3. Example (2): my buyer wanted modifications to the delivery according to NEW specifications… I wanted to add $1 for each future modification request.
