Custom sequence settings should be available when I want to modify my sequence.

For a very long time, video post production workflows were fairly fixed.  You'd set the right settings for your Sequence (usually based on delivery settings) and that was it.

But now that some video editors need to create a variety aspect ratios from the same source footage, the quicker and easier we can change settings the better.

Auto Reframe (mentioned by @PaulMurphy) can be very helpful, but doesn't allow for custom settings.  It might even be helpful to expand this feature request beyond the Sequence Settings dialog box to the Auto Reframe Sequence dialog box where users could choose "Target Sequence Preset" instead of "Target Aspect Ratio".

This is a very good idea and would be very handy to have. I totally agree

Does anyone else get frustrated by the fact that if I want to modify a sequence's settings,  the custom presets are not available and I literally have to change the sequence settings on every sequence manually.  This is relevant when you need to make, for instance, social formatted versions of edits, which I do manually since the auto format option is terrible.  Say I have 30 sequences I need to make vertical versions of, this is going to take me for ever!  A "workaround" could be to make 30 new sequences in the vertical format and paste each sequence into these, but that won't save any time.  Is there a reason custom settings are not available when modifying a sequence's settings?
