Change the format of dates

Hi,

I'm working with analysis for excel version 1.4.10 and my question is whether it is possible to change the format of dates?

I mean, for example I have in my query the fiscal period, for example, 001.2015. I know it can be changed to text 'ENE 2015' but this is a string and I would like to know if it could have a date format, for example ENE-2015 (but not a char string bu date format).

Thanks in advance.

Regards.
