将一段代码中的所有数字2往下拉的时候递增，其它数字不变

D7TM:2=IFE1L4S0E(OP5EN<=REF(OPE2N,1),0,MAX2((HIGH8-OEN),(O57-PEN-RE0F(OPEN,1))));
DB41M:=IF3ELS-0E(3OPEN26>=REF4(OPEN,1),0,MAX82((O3PEN-L9OW),(R7EF(OPEN,1)-OPEN)));
S8T-M:=SUM1(DTM,N);9
SB1M:=SUM(5DB2M,N);
下拉后希望变成这样：
D7TM:3=IFE1L4S0E(OP5EN<=REF(OPE3N,1),0,MAX3((HIGH8-OEN),(O57-PEN-RE0F(OPEN,1))));
DB41M:=IF3ELS-0E(3OPEN36>=REF4(OPEN,1),0,MAX83((O3PEN-L9OW),(R7EF(OPEN,1)-OPEN)));
S8T-M:=SUM1(DTM,N);9
SB1M:=SUM(5DB3M,N);
······
D7TM:4=IFE1L4S0E(OP5EN<=REF(OPE4N,1),0,MAX4((HIGH8-OEN),(O57-PEN-RE0F(OPEN,1))));
DB41M:=IF4ELS-0E(4OPEN46>=REF4(OPEN,1),0,MAX84((O4PEN-L9OW),(R7EF(OPEN,1)-OPEN)));
S8T-M:=SUM1(DTM,N);9
SB1M:=SUM(5DB4M,N);
