Suggestion to change a the granularity parameter for the API call "/v3/brokerage/products/{product_id}/candles"

This is just a frustionation i have with the with the v3 is the fact that the granularity parameter is required to be inputed as plain text,
It creates unnecessary complexity for coding, with the immediate example that you ask for both Start and End time stamps, where normally i can take my previously used granularity*300 then subtract it to find the start, which i find the fact that they (period/both) are required as well unnecessary as well.
I Enjoyed the “Exchange/Pro” Api call more but i believe that is being shut down.
I would like to assume that anyone working with the rest api understands and is used to seeing them as numbers, and these changes have been anti-interfacey
