Guardian automation - condition applied to all runners

[DavDvo]

Guardian automation is missing possibility to apply condition to All runners. Small example:
I want to Back In-play any runner, if Back price of the runner drops below 1.3. To achieve this it is necessary to make the same condition for each runner by Betfair order separately, which is not really user friendly. If something should be modified than it has to be done "NumberOfRunners" times. On top of that "NumberOfRunners" is changing race to race. And I guess that execution of "NumberOfRunners" conditions every refresh cycle is slower then execution of one condition applied to all runners.
