I often set up conditions for spell cooldown between X and Y values; this can be done via some combination of and-or and parenthesis. I don't think there is a solution to simplify this.

If I want to set up conditions with multiple of these ranges, the configuration will become ugly and hard to track.

For example:
(
Spell cooldown: Summon Charhound less than 33 sec
and
Spell cooldown: Summon Charhound more than 30 sec
)
or
(
Spell cooldown: Summon Charhound less than 13 sec
and
Spell cooldown: Summon Charhound more than 10 sec
)

My suggestion is to add a new operator, between.

For example:
Spell cooldown: Summon Charhound between 30-33 sec
or
Spell cooldown: Summon Charhound less than 10-13 sec
