Randomising Logic for a 3 x 2 condition without repeats

Hi all,
I am running a study with 2 independent 'author' variables, namely GENDER (male, female, org) x FORMALITY (formal, informal). This leads to 6 possible version of 'authors'. (i.e. Male Formal, Female Formal, Org Formal, Male Informal, Female Informal, Org Informal).
I have 6 texts to be presented to participants, and the 6 'authors' to are to be paired with each text, such that one author can only be paired to one text once, without repeats.
I have created all the possible conditions in separate blocks (sample):
E.g. Org F 1 denotes: Org Formal Text1 and so on.
I need to do a randomisation where

1. the text order presented to the participant is randomised (e.g. text 1, text 3, text 5...).


2. the 'author' attached to said text is randomised.

But also such that if an 'author' is used in the preceding text presented, then it will be taken out of the pool, and not available for subsequent randomisation. I have attached 3 possible outcome flows for 3 different participants here:

How do i structure the logic of the randomiser to achieve said effect? Thank you so much!!
