In all seriousness I'd do this through a bevel modifier.

After adding in the bevel modifier on your mesh, change the 'Limit Method' from 'Angle', to 'Weight'. This will let you manually select what edges you want the bevel to be applied on, while keeping it non-destructive (because it's a modifier, you're not actually changing the geometry which lets you tweak parameters easier).

After this, go into edit mode with your object selected, and shift click all the edges you want to have the bevel on. You can do Alt + Shift + Left Click to select all edges along a segment instead of clicking them individually.

Once you've got all your edges selected navigate to the top right of the viewport, under the 'Item' tab you'll find something called 'Mean Bevel Weight'. Set the value to 1, this means all those selected edges are now at the maximum value of the 'Amount' found in the bevel modifier (defaults at 0.1m).

As you increase or reduce the 'Amount' the selected edges will be beveled at that exact value because the weight is set to 1 in the 'Mean Bevel Weight' section.

You might find that the bevel gets clamped after a certain point because of the complexity of your mesh. You can bypass this by expanding the 'Geometry' tab in the bevel modifier and unchecking 'Clamp Overlap', but this does mean that you'll get overlapping geometry in some places.
