If you are in the cloud, you can install additional a MENA version of InDesign. MENA stands for Middle East North Africa and supports a lot of RTL features. You can install it above your normal version which will be extended to this functionality. RTL (Right to Left) affects a lot of function, e.g. binding of new document, story, object styles, paragraph styles, character style, cell styles, composer, compost fonts, etc. You can apply RTL on a character level, on paragraph level, on story and on document. In paragraphs you can decide if automatic bullets or numbers are left or right of the paragraph. This opens a lot of design opportunities, even if you don't want tu use it for RTL.
To install a NEMA version you have to go to the cc application and change the app language at least temporarily for installing that language.
You can also use a file from someone else, where such a style was created.
I have one here with a lot of styles: Dropbox - direction.idml
When you import the direction character styles you can apply them in any paragraph style, but you have to change the composer to one of the Adobe Global Composer, otherwise it would not work. These styles are available, even if you have not installed MENA.
