Separate "clear" buttons for each campaign

Describe the content or mechanics you are proposing.

In settings section "Game Data" instead of "Clear Research" and "Clear Campaign Saves" buttons "Clear Serpulo Campaign", "Clear Erekir Campaign", "Clear Serpulo Research" and "Clear Erekir Research" will appear. Each button will only affect data for respective planet.

Describe how you think this content will improve the game. If you're proposing new content, mention how it may add more gameplay options or how it will fill a new niche.

Present game features do not allow to clear data of different campaigns separately, even though they are not connected through gameplay. Separating "clear" buttons into planet-specific ones will fix this problem. Comment: I wanted to re-do Erekir campaign while keeping Serpulo intact (a thing many players might want to do after V8 with new features for Erekir comes out). While resetting sector data was easy through simple file manipulation, as a regular player I found it impossible to reset Erekir research without affecting Serpulo.
