The default data set prefix is the current TSO user ID. This makes it hard to list all LAT data sets as there is no common element in the qualifier. If the prefix is changed (e.g. to USER.ALA) then it is easy to list the data sets, but in case of a profile that is used by different users, everyone has to change the prefix. The enhancement request is to either support variables (e.g. &SYSUID) in the job prefix or add a level to the default qualifier (e.g. ALA).
