This is my biggest problem as well: manually linking each link in all journals as there are thousands of them. I wish there were an easier way to do this, as it takes me forever.
I guess the best approach is to link only the note for the current day (e.g., only link "✱ Home | Month | Today | ← Back • Next →") and then link each day in the month at the start of each month. I really wish there were an easier way, though, let me know if you have any tips for this guys, thanks!
