Different GL A/C FOR TAX

Dear all,

My query is ,

At the time of GR the CST is added in the GRIR Clearing a/c, Instead of that the requirement is , it should be posted in different GL A/C .

Now :-

STORES & SPARES A/C Dr. 105

GR/IR Clearing A/c - Cr. 105 (GL A/C 161230)

Requirement:-

Stores & Spares A/c Dr. 105

GR/IR clearing spares A/c - Cr. 100 (GL 16230)

GR/IR CSTclearing A/c - Cr. 5 (GL 161052 )

How to make this settings?
