Jira Portfolio resource allocation by skill set

[Joshwa Marcalle]

Hi all, 

I think I know how to use Jira portfolio very well and for the most part, I get great value from it. But, I cannot quite get the skills set feature. 

Question: How can the team estimate their stories (on the backlog) and have those estimations "land" on the corresponding skill set in portfolio without having to copy/pasting them?

Example: 

1. I have 2 iPhone devs and 2 Android devs resources, all belong to the same Scrum team
2. They take the tickets and estimate them. Example: 4 Android stories, 5 iPhone dev stories
3. I go to the portfolio, refresh the data and Portfolio assigns any ticket to any of them regardless of what the skills are on the resources. 

Am I really supposed to go down the list, ticket by ticket and copy the "Original estimate" value and paste it under the appropriate skill set? Really? 

I must be doing something wrong. I hope 

Any help here would be immensely appreciated
