Nope, because if you are a heavy calendar user there are tons of things that could be trivially shuffled. A calendly link is “I will fit you in only if it’s extremely convenient for me”.
“Here’s the link to my calendly. If you don’t see anything that works in the next week or so, just send me over a few times that would work for you & I can reshuffle things to make one of them work.”
Exactly. From my experience Calendly works 99% of time, and remaining 1% is where it is better to handle it personally than through PA.
