Additional Estimation field

[Ahern Nigh]

Is there a way to create a custom field or repurpose an existing field that would roll up into 'Original Estimate'?  I would like to split out our Original Estimate field with a 'Original QA Estimate' for granularity and more precise reporting. 
Example: 

Original estimate --> 4d

QA estimate --> 1d

Total Original estimate = 5d

Hello @Ahern Nigh 

Welcome to the Atlassian community.

There is currently not a native "Duration" type for custom fields. There are two open change requests about that to which you could add your vote.

https://jira.atlassian.com/browse/JRACLOUD-67720

https://jira.atlassian.com/browse/JRACLOUD-94778

You could create custom text or number fields and build automation to interpret the data and update the the fields.
