Hi Michael,
Another approach if you create presets that you can call for all your current and future projects.
In the delivery page, at the top left, first, you click on "Custom".
Then you make all your settings completely: format, Codec, Resolution, etc ..., audio tab and File tab, (all settings)
Always on the top left you click on the 3 small dots and you select "Save as new Preset" and give it a name. You will see in the list of presets the new preset created with its name.
You make your delivery and you test it. If it's OK, it's over, you can use it in other projects.
If you need to correct the preset, you return to the delivery tab and click on your preset. You make the modifications and always clicking on the 3 small point, you click on "Update Current Preset". (and test delivery?)
If your preset no longer serves: you can delete it

For example, I made presets for TIFFs, one in 16 bits, the other in 8 bits.
First the 16 bits
=> Save as new preset
from the 16-bit TIFF, I changed the codec: RGB 8-bit
=> Save as new preset
Now I have 2 presets for TIFF.
