AWS CloudFormation Separate Resources in Files

Question

I want to use AWS CloudFormation and  to separate my stack resources into different files without using nested stacks, How can i achieve this so as to make my template neat and structure as it could have over 50 - 100 resources.

Example  in YAML
[MainTemplete.yaml]
1. Resource1.yaml
2. Resource2.yaml
3. Resource3.yaml
4. Resource4.yaml
5. Resource5.yaml

if posible Resource5.yaml to include
1. Sub1Resource5.yaml
2. Sub2Resource5.yaml
3. Sub3Resource5.yaml

and also able to share parameters and resources.
Thank you.

I think the closest thing out-of-box is `AWS::Include `transform. However it won't allow you to do multiple levels of includes and it isn't a work-a-round for single template size limit as includes are processed before template is deployed. Make sure you check Remarks -section at below URL
