Create TO for each inbound delivery line items via output type WMTA

Dear experts

We use output type WMTA to create TO automaticlly for the inbound delivery , it' works fine.

but now the business ask to create the TO for each delivery line items.

for example .

if the inbound delivery have 3 line items. we need to create 3 TOs.

now we create one TO with 3 TO lines.

then i check the WMTA funciton , it's use the function  L_TO_CREATE_DN

i don't find the parameters for the delivery line items(LIPS-POSNR)

The question is :

can we use WMTA to create TO for each delivery line items automactilly ?

or should we enhancment the function L_TO_CREATE_DN?

Thanks. in advance!
