Reanalysis function for existing projects

For existing projects it would be handy if there was an option to reanalyze the project and add new content from the TM. We often need to halt projects to wait for other similar translations to come in. Once those translations are in, we don't have another option than to delete the initial project and create it again to have the new translations added. Other TMS do have the option to reanalyze existing projects to add new translations.
