I would like to be able to use smaller gain increments in SISOTool in Control System Toolbox 6.2 (R14SP2) to increase the locus resolution in the gain range that I am most interested in.

The ability to use smaller gain increments in SISOTool to increase the locus resolution in the gain range that is of most interest is not available in Control System Toolbox.
To work around this issue, you can use the RLOCUS function instead of SISOTool to specify a gain vector with the following syntax:
r = rlocus(sys,k)
where "k" is a vector containing the gains.
