How To Manage Multiple Phone Numbers For PV IG?

Hey guys,
I just bought dozens of Simcards and plan to use them for IG PVs but I have not thought of any effective way to manage them (maybe a cards book for keeping them and an exel file to save position of each sim in card book)
Hope I could get some good idea from you guys,
Thanks

I have a book and i do like this

I write the name of the IG account on a page and i put the sim card on that page. On next page i write the next IG account name and do the same with the next sim. (My IG accounts have names like this : MGO1, MGO2, MGO3 etc) So if i see on jarvee an account that needs PV i just go to the page of the account from my book and use the sim to verify it.

The IG account names are saved in a notepad on my PC called "Ig accounts" and there i have organized all IG accs. Under each account i have his email, his password etc.

I guess it will be alot of time consuming if you have alot of accounts but this is the way i organize my ones.

You could always code something and use that to keep a list. Or even easier, Excel, it can help you make a quick list easily, have the 4 last digit of each SIMs, IG Username, (even proxies and all).
