Crawling Origin Identifier

Is there a possibility to check if the field is being scrawled upon ?

for example
details A2 in Valuation DCF/sheet is linked to detail B2 in scrapped source sheet,
so can we check which data is scrapped in scrapped source sheet ?

The basic idea is to check whether the data in the scrapped source sheets are being indexed / crawled in another sheet or not.
