Hi @blckhwk ,
unfortunately the open source version is limited respect the hosted version.
Some feature are not implemented and there is no way to tell you how to implement it or will be simply implemented for all if was so easy to do.
The SLA feature has been already requested https://github.com/uvdesk/community-skeleton/issues/291 but for now will be not implemented.
If you need customization you can try to ask to the commercial support, this may help the project and maybe will be solve your request. You can ask for that in a ticket to the UVdesk team if you want to contribute to have the customization, if this will be possible for developers.
