Control of Locksize and Maxpartitions for implicitly defined tablespaces.

We must be able to control parameters like locksize and maxpartitions on implicitly defined tablespaces.
In DB2 V12R1M504 multi table tablespaces are deprecated, so we need to use implicitly defined tablespaces for QMF useres.  
Today we use segmented tablespaces with locksize table for these uses.
QMF users are business users with no control of commit scopes in their data manipulations.
Implicitly defined tablespaces use lock size ROW. It will cost us many lock request and lock escalations, so we want to control the locksize.
Implicitly defined table spaces use maxpartitions 256. We want to control the parameter as we well.

    Should be easy enough to add a column to Q.PROFILES so that after the table is created the contents of the extra column are used in an ALTER TABLESPACE on the implicitly created tablespace. (Before the data is inserted.)

    Another parameter that would be useful for QMF tables would be not logged.  In our shop the tables created through QMF are only temporary tables.
