In MS Project, within the View tab, there is the Timescale function which opens up a drop down to allow you to choose some default timescale views (days, weeks, months etc.)

Is there a way to alter the format of these?
eg, within the 'weeks' option, the format of the bottom tier is 26/01, 02/02... etc and I'd like to change this to 26, 02... etc rather than changing it evertime.

Thanks in advance
