Any way to create branches in a hex?

Hex Casting has a boolean iota type, but I have not been able to find any patterns which make use of the type as an input. There are plenty which push a boolean to a stack, but I cannot find a single one that pops a boolean. This led me to wonder if there's a way to use booleans to create branches. Like a conditional Hermes' Gambit that only casts the provided pattern list if a provided boolean value is true. There's an entire chapter of logical operators in the Hex Notebook, but there doesn't seem to be any pattern equivalent to an if statement.

Wait, Augur's Exaltation could be used for that.
