I want to run the following regression


Code:
reghdfe ABPROD BORDERLINE POST BORDERLINE_POST i.sic_2 DSIZE DLEV DBTM DROA DMKTCAP ABACC,noabsorb cluster(gvkey)
where sic_2 is 2-digit industry code. However, I also want to include an interaction variable for between each industry and the POST (time dummy) and BORDERLINE variables (category dummy). Is this possible without generating 19 different interactions for each industry (I have 20 industries)?

Thanks.
