How to limit order on gig extras when order queue is set to 1?

[liznov]

I'm new to Fiverr and currently still setting up my gig. My gig is on web novel editing, and I offer only one package. I have limited orders in the queue to 1 because I think I can only work on 1 order at a time. A while ago, I temporarily activated my gig to preview what it would look like to buyers, and I noticed this:

Buyers can order more than one of the same extra. For my gig, this doesn't make sense. 1 order of Section Rewriting, for example, is enough to cover the entire story. It doesn't mean I would only pick 1 section of the entire story to edit. This would just confuse buyers. Is there a way I can limit buyers to buying only one of each extra?

Thanks in advance!
