Is your request related to a problem? Please describe.

I'm trying to add some custom routes to the private subnets created through the module. I could be misunderstanding how the module/resources are working and or the current standard pattern.

I'd like to be able to manage custom route table routes for my private subnets through the module. Currently, from looking at the variables/tf files, I'm only able to add custom routes to the default_route_table which is never attached to my private subnets (again unless I'm missing a setting or option here).

Describe the solution you'd like.

Create a dynamic route option for the private subnets and or intra/database subnets to extend the route customization options.

terraform-aws-vpc/main.tf

Line 1364 in 7c1f791

resource "aws_default_route_table" "default" {

Describe alternatives you've considered.

I could create another module/resource in my Terragrunt repository to create the route table routes separately but I'm not sure why the feature is missing from the module, where the custom route option feels useful to have available at the source so to speak.
