Change entitlement file.

Hi guys!

I have a problem - I need to add some lines to .entitlements file during iOS packaging. by default it contains only “get-task-allow” key. As I understood all possible values hardcoded in Engine\Source\Programs\UnrealBuildTool\Platform\IOS\IOSExports.cs. So how can I add custom value to entitlements file (for example enable healthkit into the project)?
