Reuse Flavors for Custom transactions - sap personans 2

Hi All,

I've 4 custom transactions a,b,c,d with similar screen flow  of 5 screens. I created Flavor X ,customized all the 5 screens for transaction 'a'. which took almost 4 weeks. Now how can I reuse this flavor for the remaining transactions b,c,d. Do I have to create all over again for rest of the transactions?

Thanks in advance,

Bhaska
