Hi Knight

There a lots of combinations for Audience rules the only way to decrease this is if there someway of simplifying these for example using grade > 4 rather than a rule for every level. Once an Audience has been created then the Audience can be copied and edited 

For the Hierarchies it is possible to bulk add hierarchies - if you create a spreadsheet with the data and copy and paste this into the Bulk add for the hierarchy as follows.

Provide a list of names (one per line) to create multiple items at the same time. You can use spaces before the item names to indicate the parent-child relationships - every 2 spaces you include before the name indicates one level in the hierarchy.

You must ensure that the structure you create is valid, which means every item must either be at the top level (no indentation) or be below an existing item at the level above. Example: You cannot create a level 3 item unless there is already a level 2 item above it.

Note: This bulk add functionality is for use if you want to create simple items, in the same framework, with the same type, and with no additional information such as ID Numbers and Shortnames.

You don't have to use multiple hierarchies - you can define types for the hierarchy and each type can have fields such as Grade with the various possible options. see https://help.totaralearning.com/display/TL9/Organisation+Types for more details.
