PS Custom
Custom dependencies can be used to force precedence at any level of the block tree. This may be used to enforce a certain order of pit development, landbridge precedence and/or backfill permissions.
To add a custom dependency:
Press the Blue Plus icon to add a new rule group.
Rename the rule group (ie. mining rules, backfill rules, landbridge rules).
Using the tree hierarchy on the right, select the successor record and double click on the predecessor.
