I am not sure if there's a better strategy, but I've make sure I'm signed into the store when preparing the desired configuration and hit the "♥️" icon to make sure it is ready to go in my favourites.How do we prep to pre-order? I don't know how this works.
Can someone please shed some light?
Or you can make sure to have some tabs open / bookmarks saved with the configured products you want.
Anyway, that's the best I've been able to think of to speed things up for myself in those sleepy morning hours when the ability to add the items to the shopping cart becomes available. The idea being to get it into the cart and shipping screen ASAP, no waffling on any details or accessories in those critical moments.
EDIT: made like 5 tweak edits as I wasn't happy worth wording.
