Power Designer - Mapping Editor Question

Hi Experts

I have a very basic question on Mapping Editor Tool in PD. I have created a .PDF for 2 Tables that are within the same database. I need to map fields from Table 1 to Table 2.  Data for Table_2 comes from Table_1

Table_1               Table_2

E.Name               E.Name

Age                     Age

***                     ***

Say E.Name and Age fields are directly populated from its corresponding field value from Table_1. But for Table_2.*** the logic is

IF Table_1.*** = 'M' then

Table_2.*** = 'MALE'

Else

Table_2.*** = 'FEMALE'

Is is possible to mention this type of transformation logic while using the Mapping Editor?

Also how can i HARDCODE a value?
