multiple shadows using fullforwardshadows

I use forward rendering.
How to get multiple shadows using fullforwardshadows?

My shader :

Shader "0Diffuse1" {
Properties {
	_Color ("Main Color", Color) = (1,1,1,1)
	_MainTex ("Base (RGB)", 2D) = "white" {}
}
SubShader {
	Tags { "RenderType"="Opaque" }
	LOD 200
	CGPROGRAM
	#pragma surface surf Lambert fullforwardshadows
	sampler2D _MainTex;
	fixed4 _Color;
	struct Input {float2 uv_MainTex;};
	void surf (Input IN, inout SurfaceOutput o) {
		fixed4 c = tex2D(_MainTex, IN.uv_MainTex) * _Color;
		o.Albedo = c.rgb;
		o.Alpha = c.a;
	}
	ENDCG
}
Fallback "VertexLit"
}

This is great thank you!
Is it possible to make one that uses Spec And Bump as well?
