Multiple checkmates patterns

I am using this site. thank you.

I think it is a problem that there is only one correct answer when there are multiple checkmate patterns in a tactics problem.
(Even if it takes long steps.)
Wouldn't it be possible for an user to suggest or add the correct answer?

Sorry for my poor English.

This issue has even been reported on github and is wanted too. Here's the link github.com/WandererXII/lishogi/issues/301

Thank you for your reply.

Currently, there are some problems where the shortest step is incorrect and the second or third shortest step is correct.
(For example, lishogi.org/training/NThrX. I think the shortest step=17, but answer step=19.)

Please do send what you think is the right answer to that puzzle.
