CVR Rules

Hi ,

We are defining CVR rules for one COA structure, however hierarchy will not be defined for this COA.

Whether CVR rules will work if hierarchy is not defined? as in lets say a condition saying natural account between 1002 and 1004.

Further, in the validation filter noted that we have filters like starts with , end with - any possibility to have a custom filter like Does not start with?

Appreciate any inputs on this.

Thanks
