Title: Feature Request: Visual Merge/Bundle of Multiple Relationships Between Same Tables

Description:

Problem

Currently, when multiple relationships exist between the same two tables, each Ref creates a separate line in the diagram. This can create visual clutter and make diagrams harder to read, especially with complex schemas.

Proposed Solution

Add the ability to visually merge/bundle multiple relationship lines between the same tables into a single line with annotations.

Example Use Case

Table Order {
  id int [pk]
  customer_id int [ref: > Customer.id]
  billing_address_id int [ref: > Address.id]
  shipping_address_id int [ref: > Address.id]
}

Currently: 2 separate lines from Order to Address
Desired: 1 bundled line with labels (billing/shipping)

Suggested Syntax

Ref bundle_name {
  Order.billing_address_id > Address.id [label: "billing"]
  Order.shipping_address_id > Address.id [label: "shipping"]
}

Benefits

• Cleaner, more readable diagrams
• Better visualization of complex relationships
• Reduced visual clutter
• Common feature in professional ERD tools

Alternative

At minimum, allow grouping relationships visually with color coding or line bundling options.

Visual example:

ADR_

ref: T1.Adress - T2.ADR_STREET_NUMBER
ref: T1.Adress - T2.ADR_STREET_NAME
