when you select weekly missions category and refresh it sends you back to the daily mission category, any possible chance when we refresh it just stays in the same category?

Also is it possible to redo the mission chances as it is more common to get the legendary missions than it is to get a uncommon. for example when i am trying to go for weekly "Party Animals" mission, I skip past 2 or 3 legendary missions before I even get to the Uncommon Party Animals mission
