Automate setting DST in Sysplex with Multiple timezones

We have systems in a sysplex that have different time zones than the one specified via STP. For time zones that change for DST at the same time as the STP time zone we would like the DST change to be automated via STP.

This could be managed by introducing a new CLOCKxx statement DSTZONE STP|NONE which would apply to systems that specify STPMODE YES and STPZONE NO.

An example:
STP is using US Eastern time W.05.00.00 but there are systems in the sysplex that specify US Central time W.06.00.

Currently the systems that specify US Central time have CLOCKxx with

TIMEZONE W.06.00.00
STPMODE YES
STPZONE NO

and DST changes have to be managed manually via the SET TIMZONE command and changing TIMEZONE in CLOCKxx even though the DST change happens at the same time as the STP time zone US Eastern.

Changing CLOCKxx to

TIMEZONE W.06.00.00
STPMODE YES
STPZONE NO
DSTZONE STP

would allow the DST change to occur at the same time as the automatic DST change for the STP time zone of US Eastern.
