This is a pool of dice for you to spend at your leisure. You spend them in whatever order you want to. There's no rule to dictate which one you spend when or in what order.

Thus, spend the dice that it makes sense to spend, if you're sitting there with 8 points of damage, roll the d8 (or, well, 2 of the d6s...). 

Some folks might feel like this is a bit metagamey, those folks could randomize or create an order in which they always spend them, but that's going to be highly sub optimal. The whole process of spending HD is already slightly metagamish so I wouldn't sweat this one.

What order do multiclass characters spend Hit Dice at the end of a short rest?
I have limited experience with the Data Import Wizard but I'm curious if it allows me to create new accounts and contacts from a single csv import.

Rather then importing accounts from a csv, capturing the new SFDC accountID, updating the contacts csv file with the accountID and importing the contacts csv.

Can that be consolidated into a single csv with account and contact fields and imported through the data import wizard?
