Since there is no rhyme or reason to how long Global Entry Conditional Approval will take at this time, does anyone know if I can just pay the extra $85 Fee and submit a "separate" Application for TSA PreCheck ONLY as I wait possibly many months for GE Conditional Approval?

The reason I ask is because I will have US domestic travel in the next couple of months and would like to at least have TSA PreCheck. Also, I have multiple credit cards that will cover the Fee for Global Entry or TSA PreCheck. NOTE: I have already submitted my App and $100 Fee for GE and it is looking like it may be a long wait for Conditional Approval of this Initial Application. I would, of course, use a different Credit Card for the TSA PreCheck Fee (to receive reimbursement for that fee in addition to the GE fee). Has anyone else done this and been successful in obtaining TSA PreCheck while awaiting approval of Global Entry by submitting 2 completely separate applications and application fees?
