Duplicate sound sample in OP1 Drum Utility

Hi! I’m trying to create custom .aif for OP-Z using official OP1 Drum Utility.
While total duration is limited by 12 seconds, is there a way to duplicate same sound file to different slots (for different pitch for example) without extending total duration?
I guess there is an option to do it after transferring pack to OP-Z (by manual copying each tone) but it feels like software could do it too.
