GRS syntax is supported on certain fields as per Pega Documentation :  https://docs-previous.pega.com/data-management-and-integration/85/fields-support-global-resource-settings-syntax It would be very useful to be able to use GRS syntax also when setting BIX Extract rules output directory.  So that we could manage easily different output directories per environment.  Even if we use an activity that trigger extraction with pxExtractDataWithArgs activity, we cannot override output directory with a -P argument since it is not available when running an Extract rule with that activity(see BIX arguments doc : https://docs-previous.pega.com/data-management-and-integration/85/bix-parameters-and-command-line-arguments )
