What is the timing for refilling the two provinces when I use the ability of Wayfarer's Camp?

Will I be able to turn one of those two new cards face up with the Then effect?

You refill each province after playing the character, even though you’re not finished resolving the effects of Wayfarer’s Camp.

You can turn one of the refilled cards faceup with the post-then effect.
