New tools allow you to apply conditions (e.g. emission factors) to a group or range of sources. Applied conditions can be altered for each individual source independent of the source form without changing the conditions for all sources in a group. These tools eliminate the need to apply conditions to sources individually.
Filters simplify defining the group of sources applicable to the conditions. Simply type in the source ID filter or copy ID's from a spreadsheet.
