Automated daily lookups

[MayDayOne]

index="URL" NOT [inputlookup A_list_Jan1.csv | fields gtld]
| inputlookup A_listJan1.csv append=true
| dedup gtld
| table gtld
| outputlookup [ | stats count | eval filename=strftime(now(), "B_list%b%d.csv") | return $filename]

QUESTION:
I want to run this search daily. Is there anyway I can automate this search so that "B_list%b%d.csv" gets inserted as the first "inputlookup". This would result in the next days outputlookup as "C_list%b%d.csv".

REASON:
I see 100's of new gtld's on daily basis and I'm making a list of "total gtld's seen".

SECONDARY GOAL:
Create a second daily list of only the new gtld's seen for that day.

You could make one lookup and include the timestamp of when that ID has been first seen. Should kill both birds with one stone, an overall list and - by filtering - a list per day.

EDIT:
The top two .csv files are the same.

index="URL" NOT [inputlookup A_listJan1.csv | fields gtld]
| inputlookup A_listJan1.csv append=true
