How to design a 7400 having 4 single gates to place?


KrengelRFDesign

How can I design a 7400 (it has 4x NAND gates) so that I can place single NAND gates in the schematic editor?

What I've tried:

Using the parts/library editor I  made a new component holding that 4 NAND. As the second step I wanted to assign the ICs pins (14). Assigning the pins to the 4 NANDs wasnt a problem but it wasnt possible to assign pin7 to GND and pin14 as Vcc because these pins havent been in the assignment list/editor. What did I wrong?

Thanks for your help
