I am also trying to figure out the best way to represent Sold options that 
open new positions.

The suggested approach below works (kind of). 

2020-12-28 * "Sell March 1 PUT 200 on HOOL"
   Assets:Brokerage:Taxable:HOOL:Options   -1 HOOL_PUT_200_2021_03_01 {1000 
USD}
   Assets:Brokerage:Taxable:Cash                     1000 USD

Seems like I would need to add a new currency to HOOL:Options account each 
time I open a new position. Overtime I suspect this may result in hundreds 
(or even thousands) of currencies attached to a single account.

1) Is there any downside of attaching so many currencies to a single 
account? 
2) Is there a way to represent these transactions using the same currency 
over and over (based on the cost basis and date of options)

2020-12-28 * "STO March 1 PUT 200 on HOOL"
   Assets:Brokerage:Taxable:HOOL:Options   -1 Options {1000 USD}
   Assets:Brokerage:Taxable:Cash                     1000 USD

2020-12-30 * "BTC March 1 PUT 200 on HOOL"
   Assets:Brokerage:Taxable:HOOL:Options   1 Options {1000 USD} @ 990 USD
   Assets:Brokerage:Taxable:Cash                     -990 USD
   Income:PnL
